Driver selection incorrect when intel_pstates present. No way to override.

    • Closed Issue created by Jean-Christophe Hugly @jice

    Linux can be so frustrating.... I'm running FC39 on a Lenovo X1 yoga Gen 8. In standard configuration, the power is managed by the hardware with policy direction by the in-kernel intel_pstates driver. The platform_profile module can't manage power in that configuration (If memory serves, I saw a msg to that effect in the log).

    I found that power-profiles-daemon has a hard-coded list of drivers to use. It tries platform_profiles first and, because it's there (although incapable of managing power) it uses it. There's no way to override that choice. There's no way to remove the platform_profile module because the thinkpad_acpi modules depends on it (it'd better off without it in this case). There's no way to remove that dependency either. There's no way to remove the thinkpad_acpi module, it drives all the gadgets specific to my laptop. Note that I experimented removing both modules and that allows power-profiles-daemon to to its job flawlessly.

    As a result the power management knob in the quick settings of gnome is perfectly ineffective.

    I think it could be a simple mater to allow /var/lib/power-profiles-daemon/state.ini:Driver to override that choice. An even simpler fix might be to re-order to hard-coded list to place intel_pstate first.
